A major cause of hemolytic disease of the fetus and newborn (HDFN) is an incompatibility of the Rhesus (Rh) blood group between the mother and fetus.
To determine the prevalence of Rh c and D alloantibodies among Rh-negative women of childbearing age (18-49 years). We conducted a cross-sectional study among women who attended the antenatal, gynecology and blood donor clinics at a Tertiary Hospital in South-West Nigeria from January to August 2019. Serological typing of Rh c and D was done manually with the tube test using anti-c and anti-D antisera, while indirect antiglobulin test was then performed to screen for Rh antibodies.
Data was analyzed using Stata 16.1 software; Categorical data was summarized using frequency and percentages while continuous variables were described using the mean and standard deviation or median and interquartile range. Pearson's Chi-square (or Fisher's exact) test was used to test for association between categorical variables and Rh status. P values of ?0.05 were assumed to be statistically significant.
A total of 700 consenting women, comprising 505 pregnant (72.1%) and 195 non-pregnant (27.9%) women were recruited into this study. The mean age was 30.7 ± 4.9 years. All (100%) participants were Rhc positive while 641 (91.6%) were RhD positive and 59 (8.4%) were RhD negative. All 59 RhD negative subjects tested negative for anti-D. There was no statistically significant difference between proportion of RhD-negative women who had a jaundiced baby and the proportion of RhD-positive women who had a jaundiced baby (15.6% vs. 18.6%, P = 0.540).
This study did not identify any Rhc and D alloantibodies in the study population suggesting there is a low risk of alloimmunization and HDFN due to anti-Rhc and D in this population.

This cross-sectional study involved a retrospective evaluation of 458 orthopantomographs (187 males and 271 females) of 5-11 years old healthy Saudi children. Seven permanent left mandibular teeth were assessed as per Nolla's method to record dental age. https://www.selleckchem.com/products/gw3965.html The mean difference between dental age and chronological age was calculated using a paired t-test. Correlation between chronological age and dental age was analyzed using Pearson's correlation coefficient.
There was a statistically significant difference (P &lt; 0.05) between the estimated dental age and chronological age in all age groups irrespective of gender. The mean difference between estimated dental age and chronological age in males ranged from -2.68 to -6 months and -2.17 to -4.24 months in females. Pearson's correlation coefficient showed a strong positive correlation (r = 0.95 for males and r = 0.94 for females) between estimated dental age and chronological age.
Nolla's method is suitable for estimating chronological age in Southern Saudi children, as the mean difference between estimated dental age and chronological age was within an acceptable range.

This was a cross-sectional study.
Young adults aged 20-35 years, who presented to our outpatient clinic due to neck pain between 2016 and 2018, were examined. Cervical disc degeneration, disc placement, Modic changes, and sagittal balance were retrospectively measured using magnetic resonance imaging (MRI) in 107 relatively patients. Data about daily phone usage times of the participants were obtained by a questionnaire filled in at the time of admission.
The total number of disc distances analyzed was 535 (Group 1; n = 200, Group 2; 335). In Group 1, the disc displacement was present in 30%, and in Group 2, the disc displacement was present in 35%. In terms of DD severity, the total DD score was &gt;10 in 18 (18/40; 45%) patients in Group 1, and in 39 patients (39/67; 58%) in Group 2. The mean Cobb angle of Group 1 was 10.3° ± 6.57° (range, 2° to 34°), and that of Group 2 was 7.6° ± 5.14° (range, 1° to 26°) (Pcobb = 0.048). Modic changes were detected in 17 of the 107 patients (15.8%). Of the 17 patients, 3 (3/40, %7.5) were Group 1 and 14 (14/67, %20.9) were Group 2. MC was detected in 4 vertebrae in Group 1, and 24 vertebrae in Group 2 (P = 0.001).
The analysis of cervical spine MRI data of young adult patients with neck pain shows that the smartphone usage time is effective in cervical sagittal balance disruption, disc degeneration, and development of Modic changes.

But, it is still controversial in patients with severe oligospermia.
The aim of this study is to evaluate how varicocelectomy impacts pregnancy rates (natural or assisted reproductive techniques) in infertile couples when the male partner has severe oligospermia and history of varicocele.
A retrospective examination was made of males with total motile sperm count &lt;5 million/mL with varicocele in the period April 2013 to October 2019. Pregnancy rates were compared at the end of 1-year follow-up of 52 patients (Group 1) who underwent varicocelectomy and 36 patients (Group 2) who applied for assisted reproductive techniques without surgery. The postoperative third-month sperm parameters were compared for Group 1. Spontaneous pregnancy and conception rates with assisted reproductive techniques for Groups 1 and 2 were also investigated after 1 year.
In the semen analysis performed in the 3month, a statistically significant increase was observed in sperm number, motility, and morphology of the patients in Group 1.
